programming language syntax examples

So far: arithmetic

  ((1 + 2.3) * 7)

proposed :

  -- assignment --

  x = 3     single equal ?
  
  x <- 3    back arrow    R  

  x ← 3     

  x := 3    walrus

  x : 3     luka ... use colon for assignment

  x(3)      Matt suggests this ... hilarity ensued

  let x = 3        tiny basic

  x]3[      Quang is trying to be contrary

  x is 3     Franky suggests this 

  x is? 3    boolean

  -------------------------

  functions ... is there an anonymous function
    define
    invoke

  f(x,y)         #  by far the most common
  f x y          #  haskell

  f := {x,y | x + y}     # tom set notation ?

  f := ( x,y => x + y )    javascript fat arrow  ; math 

  if (condition) then (code block) 

  (x is? 3) => { print(x) }   # if statement that looks mathy (Tom)

  x ? yes : no                # only ternary operator

  (x ? yes)                   # minimal if statement 

  luka in the chat : 

  "x is 3" -> assignment      Jim's reaction : clever ... but maybe too clever
  "is x 3" -> boolean

  ....

  Jim says ... "is" is sounding popular.

  Quang : instead of ; between statements, use period ... more like english.
          If so, will need to enforce whitespace to avoid confusion with decimals.
          Either period plus whitespace or period plus newline maybe.

  -------------------------

  print(x)

  if x == 3 then print(x)
